4.4.1.2. Practical protective equipment should be provided when entering toxic places, such as wearing gas masks, windshield masks, etc.

4.4.1.3. Strengthen ventilation to discharge poisonous gas as soon as possible.

4.4.2. Prevention of heat stroke.

4.4.2.1. For summer construction, adjust work and rest times, avoid high-temperature construction, increase the number of breaks between work, and shorten the duration of labor.

4.4.2.2. Set up a tea kiosk at the construction site to provide tea (or boiled salt water), and cold drinks if possible.

4.4.3. Prevention of electro-optical ophthalmia and dermatitis.

4.4.3.1. Issue necessary protective equipment to welders, such as protective shields, protective glasses, protective overalls, protective gloves, etc.

4.4.4. Prevention of pneumoconiosis.

4.4.4.1. Distribute dust masks to concrete workers and welders to reduce the harm of dust. Pay attention to worker hygiene, change work clothes and bathe frequently.

4.4.4.2. When the workload is heavy, drinks to prevent pneumoconiosis, such as brown sugar water, should be provided.

4.4.5. Prevention of noise deafness.

4.4.5.1. Cotton earplugs, earmuffs, and helmets can be issued to construction workers in construction sites with loud noise to reduce the harm of noise to people.

4.4.5.2. Arrange work and rest time reasonably and stay away from the noisy environment during rest.

5. "Three treasures, four mouths" and edge protection

5.1. Safety helmet

5.1.1. Safety helmet is used to protect the head. Personal protective equipment to prevent objects from hitting the head and your own head from accidentally hitting objects.

5.1.2. Anyone entering the construction site must wear a safety helmet correctly. Safety helmets should comply with the national standard GB2811-89 "Safety Helmets".

5.2. Safety belt

5.2.1. Safety belt is a protective equipment to prevent workers working at height from falling.

5.2.2. Seat belts should comply with the national standard GB6095-85 "Seat Belts". Newly purchased seat belts should have a quality certificate and factory date, and should be tested regularly.

5.3. Safety net

5.3.1. Safety net is a net used to prevent people and objects from falling, or to avoid and reduce the damage caused by falls and objects.

5.3.2. Safety nets must obtain a license from the local construction safety supervision and management department before they can be used.

5.3.3. The specifications and materials of the safety net comply with the national standards GB5725-1997 "Safety Net" and GB16909-1997 "Dense Mesh Safety Net", and every 100㎝2 of the dense mesh safety net The mesh number of the area shall be no less than 2000 meshes. The performance of the durability test meets the requirements.

5.4. "Four Ports" Protection

5.4.1. The stairwells, elevator shafts, passageways, and reserved openings of the project under construction shall comply with the "Safety of Working at Heights in Construction Construction" Protection is required by Technical Specifications (JGJ80-91).

5.5. Edge protection

5.5.1. Projects under construction, leading to the edge of the balcony where railings have not been installed, the perimeter of the roof without parapet, the perimeter of the frame engineering floor, Three guardrails of 1.2m and 1.5m high must be installed on both sides of the stairs and the unloading platform, and safety nets must be hung.

5.6. Other safeguard measures

5.6.1. The implementation of environmental sanitation at the construction site shall be divided into responsibilities. Establish a sanitation management system and set up two full-time on-site cleaners. Construction waste should be piled up in a centralized manner. Domestic waste should be set up with special dustbins, covered, and removed every day. Ensure that living and working areas are kept clean and tidy.

5.6.2. Reasonably arrange greening facilities on both sides of the site gate and in the vacant spaces in the office, living and working areas to beautify the environment.

5.6.3. For night construction, apply for a night construction permit from the environmental protection department and notify surrounding residents.

5.6.4. Try to control the impact of noise during operation, and try not to use or use equipment with excessive noise as much as possible. Take protective measures during construction to reduce noise to a minimum.

5.6.5. Set up drainage ditches in the site to ensure that sewage does not flow out and there is no accumulation of water in the site. The wastewater from the site is discharged into the urban drainage pipe network after settling in the sedimentation tank. Wastewater from construction site toilets and canteens is discharged into nearby drainage pipes after being treated with septic and oil separation.

5.6.6. Bulk items such as sand and gravel must be transported in fully enclosed vehicles and the vehicles must not be overloaded.
